In the 70s of the last century, Canadian agricultural scholars used traditional breeding methods to breed low erucic acid and low glucosinolated double low oilseed rape, in order to distinguish it from ordinary oilseed rape, it was named "Canola", which is the abbreviation of Canada Ola or Canada Oil Low Acid. Later, "Canola Oil", which was made from this canola seed, gradually replaced the traditional canola oil, and began to be widely eaten in Canada, and was sold in the United States, Japan and other places. Canola Oil is the canola oil called in Chinese, compared with traditional rapeseed oil, its erucic acid and glucosinolate content is lower, but it is classified as canola oil in national standards, which is a kind of rapeseed oil.
 
As the country of origin, Canada is the world's largest exporter and consumer of canola oil. In the neighboring United States, canola oil is also the second largest edible oil in sales after soybean oil, but considering that soybean oil has more commercial uses, canola oil has actually become the most commonly used vegetable oil in American households, among which the most familiar canola oil brand for American consumers is none other than Correy. Kerui is the first brand of vegetable oil in the United States, founded by Procter & Gamble in 1911, the same year launched the world's first shortening made of vegetable oil, at that time as a substitute for animal fat and butter quickly swept the United States, in 2007 also developed a "zero trans fatty acid" shortening, so far Kerui vegetable shortening is still popular with American families, affectionately known as "grandma's taste".
 
Kerui launched canola oil products as early as 1988, many years of experience in vegetable oil production has laid a good foundation for it, the technical level and product quality are in the leading position in the industry, the canola oil produced is light and soft, clear and shiny, high smoke point, whether it is high-temperature frying and stir-frying, or low-temperature cooking oil can be competent.
 
The unsaturated fatty acid content of canola oil is generally about 93%, and saturated fatty acids are thought to be related to heart diseases such as coronary heart disease in mainstream research, and the "American Dietary Guidelines" mentions a large amount of evidence that the consumption of unsaturated fatty acids instead of saturated fatty acids can reduce the risk of heart attacks, especially polyunsaturated fatty acids. From this point of view, the fatty acid ratio of canola oil is more in line with the concept of modern people's pursuit of healthy diet, and the polyunsaturated fatty acid content of Kerui canola oil is more than 64%, which is better than the average level of 61% on the market.
 
As a commonly used vegetable oil, it is natural to compare canola oil with oils such as olive oil and peanut oil. Olive oil has a similar ratio of fatty acids to canola oil, and has the unique flavor of olives, but it has a low smoke point and is not suitable for high-temperature cooking. Compared with canola oil, peanut oil has a higher content of saturated fatty acids, but it has more flavor substances and a very strong flavor, which is widely welcomed by domestic consumers. In contrast, canola oil has a light smell, and Kerui adopts a leaching process with a high oil yield, most of the flavor substances and nutrients are lost in the refining process, and the refined oil can almost be said to be "tasteless", which is also suitable for cooking light dishes such as tofu and seafood. However, in the daily use of oil, different vegetable oils contain different types of fatty acids and their proportions, in order to meet the body's demand for different fatty acids, it is recommended to change the oil every 1-2 months to cook.
 
THERE ARE TWO TYPES OF CANOLA OIL, PURE CANOLA OIL AND CANOLA OIL AND OMEGA-3 DHA, THE FORMER IS A BASIC VERSION AND IS VERY RARE TO CLEARLY LABEL THE ALA CONTENT - "CONTAINS 1290 MG OF ALA PER SERVING". ALA is linolenic acid, which is an omega-3 series polyunsaturated fatty acid, which is an important raw material for the synthesis of "brain gold" DHA. In the reference dietary intake established by the National Academy of Medicine (IOM) of the United States, the recommended daily intake of ALA for adult men is 1.6g and for women is 1.1g, according to the official data, if the daily intake of edible oil is 25g, PURE CANOLA OIL can provide 2303mg of ALA, which is met by both men and women, of course, without any loss. THE SAME IS TRUE FOR CANOLA OIL AND OMEGA-3 DHA, WHICH IS OFFICIALLY "1250MG PER SERVING", WHICH IS AT THE MIDDLE AND UPPER LEVEL OF THE INDUSTRY.
 
IN ADDITION, CANOLA OIL AND OMEGA-3 DHA IS DIFFERENT FROM THE BASIC MODEL BY ADDING DHA ALGAL OIL, ASCORBYL PALMITATE AND TOCOPHEROL, ETC., AND THE PROMOTION POINT IS THAT THE OIL CONTAINS DHA. As the main component of cell membranes, DHA plays an important role in the composition of nerve cells and retina, and plays a positive role in the intellectual and visual development of fetal infants. However, edible oil needs to be cooked at high temperature before consumption, and the DHA in it is easy to be oxidized when heated, thus losing its activity, and the regulatory function of the body is also significantly weakened, and the DHA content in the edible oil itself is less, such as the product contains 32mg of DHA per serving, according to the maximum recommended daily intake of edible oil, it is only about 68mg, the overall effect is not large, consumers do not need to blindly pursue.
 
Unfortunately, there is no official purchase channel for CANOLA in China, Amazon in the United States costs 15-30 yuan, PURE CANOLA OIL includes 473ml, 946ml and 1.42L four sizes, CANOLA OIL AND OMEGA-3 DHA only 473ml small bottles.
